1.6 Permissible process pressure
Thepermissibleprocesspressureisspeciedonthetypelabelwith
"Processpressure",seechapter"Conguration".Forsafetyreasons,
this range may not be exceeded. This applies even if a measuring cell
with a measuring range (order-related) higher than the permissible
pressurerangeoftheprocessttingisinstalled.

3.1 General instructions for use of the instrument
Protect your instrument against moisture ingress through the following
measures:
• Use the recommended cable (see chapter "Connecting to power
supply")
• Tighten the cable gland
• Whenmountinghorizontally,turnthehousingsothatthecable
gland points downward
• Loop the connection cable downward in front of the cable gland
Thisappliesmainlytooutdoorinstallations,inareaswherehumidityis
expected (e.g. through cleaning processes) and on cooled or heated
vessels.
3.2 Ventilation and pressure compensation
Thelterelementismountedintotheelectronicshousing.Ithasthe
following functions:
• Ventilation of the electronics housing
• Atmospheric pressure compensation (with relative pressure meas-
uring ranges)
→ Incaseofhorizontalmounting,turnthehousingsothatthelter
element points downward after the instrument is installed.This
provides better protection against buildup.

4.1 Connection
The voltage supply and signal output are connected via the spring-
loaded terminals in the housing.
Connection to the display and adjustment module or to the interface
adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the
electronics.Todothis,lifttheterminalblockwithasmallscrewdriver
andpullitout.Whenreinsertingtheterminalblock,youshouldhearit
snap in.
Proceed as follows:
1. Unscrew the housing lid
2. Loosen compression nut of the cable gland and remove blind
plug
3. Removeapprox.10cm(4in)ofthecablemantle(signaloutput),
strip approx. 1 cm (0.4 in) insulation from the ends of the indi-
vidual wires
4. Insert the cable into the sensor through the cable entry
Fig. 3: Connection steps 5 and 6
5. Insert the wire ends into the terminals according to the wiring plan
Information:
Solidcoresaswellasexiblecoreswithwireendsleevesareinsert-
eddirectlyintotheterminalopenings.Incaseofexiblecoreswithout
endsleeves,presstheterminalfromabovewithasmallscrewdriver,
theterminalopeningisthenfree.Whenthescrewdriverisreleased,
the terminal closes again.

6. Check the hold of the wires in the terminals by lightly pulling on
them
7. Connectthescreentotheinternalgroundterminal,connectthe
outer ground terminal to potential equalisation in case of power
supply via low voltage
8. Connect the lead cable for power supply in the same way accord-
ingtothewiringplan,inadditionconnectthegroundconductorto
the inner ground terminal when powered with mains voltage.
9. Tighten the compression nut of the cable glands.The seal ring
must completely encircle the cables
10. Screw the housing lid back on
Theelectricalconnectionisnished.
Information:
The terminal blocks are pluggable and can be removed from the
housinginsert.Todothis,lifttheterminalblockwithasmallscrewdriv-
erandpullitout.Wheninsertingtheterminalblockagain,youshould
hear it snap in.
